ArmorWall Below Grade FR SIS

DuPont™ ArmorWall Below Grade Fire-Rated (FR) Structural Insulated Sheathing (SIS) is a factory-waterproofed exterior insulated wall sheathing product used in Below Grade applications.

ArmorWall Below Grade FR SIS combines the strengths of ArmorWall FR SIS™ with built in returns, proprietary below grade waterproofing, and a third party below grade dimpled membrane.

Insulating the slab with ArmorWall Below Grade FR SIS brings the transition point between it and the above grade materials to a level above the slab edge, eliminating a seam that is otherwise a vulnerable point for water and moisture intrusion.

ArmorWall Below Grade FR SIS is an incredibly durable exterior sheathing product that withstands post-construction damage to the slab edge often caused by landscaping crews working around the building’s foundation.

Having undergone rigorous testing, ArmorWall Below Grade FR SIS allows projects to meet continuous insulation (ci), building codes, and construction schedules faster and cost effectively.
